\begin{array}{l}\phantom{28)}\phantom{1}\\28\overline{)322}\\\end{array}
Use the 1^{st} digit 3 from dividend 322
\begin{array}{l}\phantom{28)}0\phantom{2}\\28\overline{)322}\\\end{array}
Since 3 is less than 28, use the next digit 2 from dividend 322 and add 0 to the quotient
\begin{array}{l}\phantom{28)}0\phantom{3}\\28\overline{)322}\\\end{array}
Use the 2^{nd} digit 2 from dividend 322
\begin{array}{l}\phantom{28)}01\phantom{4}\\28\overline{)322}\\\phantom{28)}\underline{\phantom{}28\phantom{9}}\\\phantom{28)9}4\\\end{array}
Find closest multiple of 28 to 32. We see that 1 \times 28 = 28 is the nearest. Now subtract 28 from 32 to get reminder 4. Add 1 to quotient.
\begin{array}{l}\phantom{28)}01\phantom{5}\\28\overline{)322}\\\phantom{28)}\underline{\phantom{}28\phantom{9}}\\\phantom{28)9}42\\\end{array}
Use the 3^{rd} digit 2 from dividend 322
\begin{array}{l}\phantom{28)}011\phantom{6}\\28\overline{)322}\\\phantom{28)}\underline{\phantom{}28\phantom{9}}\\\phantom{28)9}42\\\phantom{28)}\underline{\phantom{9}28\phantom{}}\\\phantom{28)9}14\\\end{array}
Find closest multiple of 28 to 42. We see that 1 \times 28 = 28 is the nearest. Now subtract 28 from 42 to get reminder 14. Add 1 to quotient.
\text{Quotient: }11 \text{Reminder: }14
Since 14 is less than 28, stop the division. The reminder is 14. The topmost line 011 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 11.
